Starting a nonprofit in Connecticut

Everything below is generated from the same Connecticut rules dataset that powers your guided journey in the platform — filing forms, real fees, and the traps DIY templates fall into.

Incorporation

Filing
Certificate of Incorporation — Nonstock Corporation
Agency
Connecticut Secretary of the State
State fee
$50 — never marked up by us
Processing
Online filings via business.ct.gov typically process in 2–5 business days
Expedite
Not offered
Watch out
  • Connecticut calls nonprofits 'nonstock corporations' — searching for a 'nonprofit corporation' form leads people astray.
  • The standard certificate does NOT include the IRS-required 501(c)(3) purpose and dissolution clauses — they must be added to the certificate text.
  • An Organization and First Report is due shortly after incorporation ($50) — a separate filing many founders miss.

Ongoing compliance

Registered agent
Must have a Connecticut street address and accept the appointment; the corporation cannot serve as its own agent.
Charitable registration
Required — Connecticut Department of Consumer Protection, Charities Unit. Initial: $50. Renewal: Annual — $50 renewal, due 11 months after fiscal year end. Required before soliciting. Exempt if you raise under $50,000 a year and use no paid fundraisers (file the exemption claim — it isn't automatic).
Annual report
Annually by the last day of the anniversary month, filed online at business.ct.gov — $50
State tax exemption
Income tax exemption follows the IRS determination. For sales tax exemption on purchases, present CERT-119 with your IRS determination letter — no separate state application, but you need the federal letter in hand first.
